PATENT QFFICE.

WILLIAM WEST, OF DENVER, COLORADO.

DRINKING VESSEL.

Application filed May 12,

To all ivo/10m t may concern.'

Be it known that I, IVILLIAM lVEsT, a citizen or' the United States,residing at Denver, in the county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Drinking Vessels,ofrwhich the following is a specification.

This invention relates to water vessels and its primary obj ect is toprovide in combination with a suitable container, means by which it maybe partially or completely lled from a source of liquid under pressureover which it is supported.

My invention is of particular value for use on drinking cups to fill thesame with water from a drinking fountain of the type commonly known asbubbling cups, and it is in this connection that it has been Shown inthe accompanying drawings.

I desire it understood however, that without material changes in theconstruction o r arrangement ot its parts, the invention may beeffectively applied to other vessels, suoli as bottles, buckets, waterbags, etc., and that in using the word vessel in the followingdescription and the thereunto appended claim, I include any container ofsuitable size and form to which my improvements are applicable.

In the drawings in the various views of which like parts are similarlydesignated,

Figure l represents asectional elevation of a drinking cup to which myinvention is applied;

Figure 2, a section take-n on the line 22 Figure l; and

Figure 3` a bottom view of the cup looking in the direction of the arrow3, Figure l.

Referring more particularly to the drawings, the reference character 5designates a drinking cup ot the well known collapsible type, in theconstruction of which are included a bottom section 6, and a pluralityof superimposed telescoping annuli 7 which in their extended positionform the wall of the vessel.

The improvements constituting the present invention consist in providingthe bottom of the vessel with a depression 8 and perforating saiddepression as at 9 for the iniiow of water from a source over which the@up is supported,

1922. Serial No. 560,501.

A disk shaped valve 13 loosely iitted in the depression normally coversthe perforations, and it is limited in its upward movement by a headedguide pin 10 which extends through a central aperture of the depression.

The valve-seat Jformed by the depression is preferably made ofsufiicient diameter to extend over the greater part of the bottomv ofthe vessel, and the latter may be provided with an annular foot 12 whichspaces the perforated bottom and the downwardly projecting guide pinfrom a surface on which the vessel is supported.

In the operation of my invention, the cup is held over a drinkingfountain of the bubbling cup type or other source of liquid underpressure. The water forcibly entering through the perforations in thebottom of the vessel lifts the valve to the extent of its limited upwardmotion, and passing around the edge of the same, rises in the vesseluntil it is completely illed.

lVhen the desired quantity of water has thus been obtained, the vesselis removed from the source of supply and the weight of the water in thevessel pressing the valve to its seat, closes the perforations againstthe outflow of the water,

Having thus described my invention, I desire it understood thatvariations in the form and arrangement of the parts may bc rcsorted toto adapt the device for use on drinking cups or other vessels whichdiffer in construction from the cup shown in the drawings.

That I claim and desire Letters Patent is:

As a new article of manufacture, an open top vessel having in its bottoman inlet for water from a source above which the vessel is held, and avalve controlling the inlet and including a guide member extendingthrough the bottom, the vessel having a base adapted to space thebottoni of the vessel from a surface upon which it is supported,sutciently to permit the valve to rest in closed position upon. thebottom.

In testimony whereof I have aiiixed my signature.
